R&B Singer-songwriter Sevyn Streeter was scheduled to sing the national anthem ahead of the 76ers’ season against Thunder earlier this week, but that performance didn’t happen.

Sevyn, 30-years old, was slated to perform the national anthem on Wednesday night (October 26th), ahead of the Philadelphia 76ers‘ season debut against the Oklahoma City Thunder, the game took place at the Wells Fargo Center. Matters transpired when the management of Sixers got wind of Streeter’s shirt. They took issue with the ‘Don’t Kill The Fun’ singers shirt, which read ”We Matter” in support of the Black Lives Matter movement.

Her performance was replaced last minute.

In front of this situation, Sevyn Streeter took her twitter on Wednesday night to explain the situation to her fans. She claims that she was supposed to sing the national anthem at the game, but the organization denied the opportunity to do it because she was wearing a jersey that read ”We Matter”.

“I’m at the 76ers game to sing the national anthem, and the organization is telling me that I can’t because I’m wearing a ‘We Matter’ jersey.” She said. This problem came a day after the NBA ”Together’ campaign, promoting unity in the wake of the protests during the national anthem by 49ers quater back Colin Kaepernick.”

The 76ers spoke on the incident, issuing their statement to USA TODAY Sports:

“The Philadelphia 76ers organization encourages meaningful actions to drive social change. We use our games to bring people together, to build trust and to strengthen our communities. As we move from symbolic gestures to action, we will continue to leverage our platform to positively impact our community.”

Few days later (October 28th), The Philadelphia 76ers apologized to Streeter, apparently several players were upset with the problem and the Sixers invited her back to sing at another game:

“After receiving feedback from our players, basketball operations staff and ownership group, we believe that the wrong decision was made, and Sevyn should have been welcomed to sing.”

“We apologize to her, and in an effort to move the conversation forward, we have reached out to offer her an opportunity to return and perform at a game of her choice. We are waiting to hear back.”
